Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. You can purchase an OBDII scanner at most Automotive Retail stores (Car Quest, AutoZone, PepBoys, O'Riely's, NAPA, even Sears, K-Mart, WalMart, etc.) - prices differ depending on features of the scanner - shop around.
There are NUMEROUS systems monitored by the ECM and too little space here to list them all. Guess work is not my style - several systems can have intermittent problems and when the ECM doesn't detect it/them again, it will turn the Check Engine light OFF. For example, one of these is the Oxygen Sensors (O2snsr). When an O2 sensor starts to go bad (intermittent malfunction), the ECM will set the appropriate DTC... If it doesn't detect it again, let's say two key cycles later, it will turn the light 'OFF', but keep the DTC stored in the computer as a HISTORY code. It also keeps count as to the number of times the DTC was set.

Low compression in cylinder 1 and burning oil

If your rings are worn or the cylinder wall is gouged, pressure will escape and oil will leak into the cylinder and get burned. Keep your eye on the oil level and you should be ok for a while. If you live in a warm climate, you might try a slightly heavier weight oil.

Hello, sounds like you may have a engine miss, things like spark plugs, plug wires, fuel injectors can cause a engine miss. you will need to have the system scanned for trouble codes. once a trouble code has been pulled form the system you will have a much better idea what the problem might be

I have a 2005 toyota corolla with 44,000 miles the engine light just went on. I know it is time for an oil change, and the car sounds and drives fine, please help

Check that your gas cap is on tight (clicks). Take your car to an auto store and have them read the codes(usually free). They can tell you what the codes mean. You may only need a new oxygen sensor. I have a Mitsubishi that the light regularly turns on in the winter and off in the summer(196,000 miles). Gas mileage is stable. Your car is newer but a road trip may be all it needs to turn off the light.

There is a button on the right side of the dash if your looking at the steering wheel.
Push the button again and should turn off the power light.

This is an option for climbing hills or when you need a little more from the motor.

The check engine light could mean anything. If the car is running ok then continue on your trip and when you come to an Autozone or Advance auto have them hook up their protable scanner to your Kia's ecm (computer) and they can tell you what the code is and how to fix it.

Don't panic and enjoy the rest of your trip.

ECU Code 4 on 1989 Honda CRX si

No one can tell you what other problems you would have, they would be playing GOD. Anyway the crank angle sensor is built into the distributor and you should change it asap. An option is to get one from a junk/used car yard. If you wanted it re-manufactured Autozone will have it with lifetime warranty.

Check engine light on

I had the same problem. I went to the kia dealer and they checked the code that caused the light to be on and found I had a leak in the gas cap. They replaced the gas cap and the problem went away. You night need to find out what made the check engine light go on in the first place.
